What You’ll Need

• 1 ½ cups old fashioned or rolled oats
• 1 ¼ cups flour
• ½ cup sugar
• 1 ½ teaspoons baking powder
• 1 teaspoon baking soda
• ¼ teaspoon salt
• 1 teaspoon cinnamon
• pinch of ground nutmeg
• 1 whole egg
• ¼ cup oil
• 1 teaspoon vanilla extract
• 1 ½ cups mashed ripe bananas (about 3 to 4 bananas)
• ½ cup old fashioned oats
• ¼ teaspoon cinnamon
• 2 tablespoons brown sugar
• 2 tablespoons melted butter

Step-by-Step Method

1. Preheat oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners or spray with nonstick spray.
2. Combine oats, flour, sugar, baking powder, baking soda, cinnamon, nutmeg, and salt in a large bowl and whisk to blend.
3. Whisk the egg, oil, and vanilla in a smaller bowl until smooth.
4. Pour the wet mixture into the dry ingredients and stir gently just until combined (do not overmix).
5. Fold in the mashed ripe bananas until no dry streaks remain; if using rolled oats, let the batter rest 5–10 minutes to soften the oats.
6. Scoop the batter into the prepared muffin cups, filling each about 3/4 full.
7. Mix the topping oats, cinnamon, brown sugar, and melted butter in a small bowl and sprinkle evenly over each muffin.

8. Bake for 18–20 minutes, until a toothpick inserted into the center comes out clean and the tops are lightly golden.

9. Remove muffins from the oven and let cool in the tin for about 5 minutes, then transfer to a wire rack to cool completely.

Tips for Best Results

• Use really ripe bananas — the browner and softer, the better for natural sweetness and moistness.
• Mix the batter gently and just until combined to keep your muffins fluffy, never dense or heavy. For a quick visual of that “just-until-combined” technique, see this one-bowl zucchini bread recipe for beginner bakers.
• Rest the batter for 5–10 minutes if using whole oats — this softens them and makes your muffins tender.
• Paper liners or nonstick spray help your muffins come out perfectly without sticking.
• Cool completely before storing so they stay fresh and don’t get soggy inside your container.

Mix-Ins and Swaps

Want to switch up your banana oat muffins? Here are some fun ways to customize:

• Chocolate chip banana oat muffins: Toss in ½ cup of mini or regular chocolate chips for a sweet surprise in every bite. If you love extra-chocolatey bakes, try these healthy chocolate zucchini muffins.
• Blueberry banana muffins: Fold in fresh or frozen blueberries for a juicy pop of flavor.
• Vegan version: Swap egg for a flax egg and use plant-based yogurt or milk instead of dairy.
• Peanut butter swirl: Drop in 1–2 tablespoons of peanut butter and swirl gently into each muffin before baking.
• Nutty crunch: Add chopped walnuts, pecans, or almonds for added texture and flavor.
• Tropical twist: Mix in shredded coconut and small pineapple chunks for a bright, sunny flair.

Storage and Make-Ahead

• Room temperature: Keep your banana oat muffins fresh in an airtight container for up to 3 days.
• Refrigerator: Store them for up to 5 days if you want to stretch them out a little longer.
• Freezer: Freeze in a single layer first, then move them to a freezer-safe bag or container for up to 3 months. When you want one, just warm it up in the microwave for about 30 seconds or the oven at 300°F. For another make-ahead breakfast bake, try Zucchini Bread: The Ultimate Easy Recipe for Cozy Mornings.

Answers to Common Questions

Can I use instant oats instead of rolled oats?

Yes! Instant oats work fine and give a softer texture, but rolled oats add more chew and heartiness to the muffins.

What’s the best egg substitute?

Flax eggs or chia eggs are my top picks here. Just mix 1 tablespoon ground flaxseed or chia seeds with 3 tablespoons water for each egg, let it sit a few minutes, then use it like a regular egg.

Why are my muffins dry or dense?

Overmixing the batter can make muffins dense, and not using enough ripe banana might dry them out. Also, be careful not to overbake — keep an eye on them and do the toothpick test at 18 minutes.
